Wheels Manufacturing T47A to 29mm Bottom Bracket w/ABEC-3 Bearings Info
The Wheels Manufacturing T47A to 29mm Bottom Bracket is built for frames with a T47 threaded shell — specifically those requiring the T47A standard found on select performance road frames — and accepts 29mm spindle cranks. Machined aluminum cups thread directly into the shell using a familiar BSA-style interface: left-hand thread on the drive side, right-hand thread on the non-drive side. That means straightforward installation without the guesswork or press-fit headaches.
Inside each cup, ABEC-3 rated bearings handle the load — and when they eventually wear, they're designed to be serviced or replaced without swapping the entire unit. A sleeve fits between the cups to seal out dirt and debris while keeping cables and hoses clear of the spindle area, which matters on bikes where internal routing runs close to the bottom bracket shell.
